    光果甘草高效二-C-糖基转移酶的功能表征和结构基础
    摘要:
    从药用植物光果甘草中发现了一种高效的二-C-糖基转移酶GgCGT。GgCGT 催化含氟丙酮底物的两步二 C-糖基化,转化率 >98%。为了阐明 GgCGT 的催化机制,我们分别解析了其与 UDP-Glc、UDP-Gal、UDP/根皮素和 UDP/nothofagin 复合物的晶体结构。结构分析表明,糖供体选择性受糖羟基与 D390 和其他关键残基的氢键相互作用控制。GgCGT 的二 C 糖基化能力归因于宽敞的底物结合隧道,G389K 突变可以将二 C 糖基化转换为单 C 糖基化。GgCGT 是第一个具有晶体结构的双 C-糖基转移酶,以及第一个含有糖受体的复杂结构的C-糖基转移酶。这项工作有利于开发有效的生物催化剂,以合成具有药用潜力的 C-糖苷。

    Flavonoids are a large group of plant secondary metabolites with a variety of biological properties and are therefore of interest to many scientists, as they can lead to industrially interesting intermediates. The anaerobic gut bacterium Eubacterium ramulus can catabolize flavonoids, but until now, the pathway has not been experimentally confirmed. In the present work, a chalcone isomerase (CHI) and
    黄酮类化合物是一大类具有各种生物学特性的植物次生代谢产物,因此许多科学家都对其感兴趣,因为它们会导致工业上有意义的中间体。厌氧肠细菌Eubacterium ramulus可以分解黄酮类化合物,但是直到现在,该途径还没有被实验证实。在目前的工作中,可以通过全基因组测序和基因基序搜索来鉴定查尔酮异构酶(CHI)和烯酸还原酶(ERED)。即使在有氧条件下,这两种酶也已被成功克隆并以其活性形式在大肠杆菌中表达。的分解代谢途径E.桂枝被黄烷酮的生物转化成二氢查耳酮证实。工程表达两种酶的大肠杆菌菌株用于几种黄烷酮的转化,从而强调了这种生物催化级联反应的适用性。

  • Engineering an <i>O</i>‐methyltransferase for the Regioselective Biosynthesis of Hesperetin Dihydrochalcone

    Abstract

    Directed evolution of the O‐methyltransferase ZgOMT from Zooshikella ganghwensis focusing on active site residues resulted in highly regioselective biocatalysts (regioisomeric ratios up to 99 : 1) for the preparation of the taste active hesperetin dihydrochalcone and related compounds. These newly constructed enzyme variants provide an attractive synthesis route for para‐methylation of catechol scaffolds, which is challenging to perform with high regioselectivity utilizing wild‐type O‐methyltransferases.

    摘要 通过对来自 Zooshikella ganghwensis 的 O-甲基转移酶 ZgOMT 进行以活性位点残基为重点的定向进化,产生了高区域选择性生物催化剂(区域异构体比高达 99 : 1),可用于制备具有味觉活性的橙皮素二氢查尔酮和相关化合物。这些新构建的酶变体为儿茶酚支架的对位甲基化提供了一条极具吸引力的合成路线,而利用野生型 O-甲基转移酶进行高区域选择性的对位甲基化具有挑战性。
